Background:
Athletes exhibit deficits in knee proprioception following anterior cruciate ligament reconstruction. Neuromuscular training programs improve knee proprioception in uninjured athletes; however, the effects on knee proprioception in athletes who have undergone anterior cruciate ligament reconstruction is not well understood. The purpose of this study was to examine the effects of a neuromuscular training program on knee proprioception in athletes who have returned to sport following anterior cruciate ligament reconstruction.
Methods:
Twenty-four male athletes, who had undergone anterior cruciate ligament reconstruction within the previous 6-12 months and returned to sport, participated in this randomized controlled trial. Athletes were randomly allocated to an experimental group (n = 12) that took part in an 8-week neuromuscular training program or a control group (n = 12) that simply continued their typical training routine. Knee position sense was assessed at baseline and after the 8-week period (post-testing). One-way analysis of covariance, with baseline performance included as a covariate, was used to compare knee position sense errors for the reconstructed limbs of the experimental and control groups at the post-testing time point.
Findings:
Knee position sense errors decreased by 51.7% for the experimental group and only 4.4% for the control group over the 8-week period. As a result, the experimental group demonstrated lower knee position sense errors, compared to the control group, at the post-testing time point (P < .001).
Interpretation:
Athletes with a history of anterior cruciate ligament reconstruction may benefit from participation in a neuromuscular training program, even after completing post-operative rehabilitation.
